*”CAN YOU POST ADVICE ON HOW TO WRITE FORESHADOWING?”*

Of course!!

Theres multiple different ways to write foreshadowing. I dont exactly got an idea on how I will explain it so I will give you 3 separate examples.
One from a piece of media, one from me, and a made up one.
This first one I am going to be using the internet show Red Vs Blue as an example. Blatant spoilers for this show.

A new character joined the main ensamble cast after they crash landed to protect them form dangerous forces.
This new guy gave the cast information, supplies, and even taken bullets to the leg for them.
So this guy he warns of an incoming battle and that they need to get prepared.
The main cast now trusts this guy, they give him a list of all the ammo and weapons on hand and potential weak points in the canyon.
So they fortified the canyon and fight the incoming battle only to lose.

Turns out when its revealed next season that this guy and the opposing army is working together. So when he gained their trust he was able to get the details of all their weapons and supplies to the enemy so they will be outmatched.

Now foreshadowing dont have to be always upfront in your face.
Some background foreshadowing;
This is a example from my future Halloween themed series. It is a spoiler but it’d be revealed within the first few episodes so-

Context:
(Part of the reason why this is a revelation is bc God ONLY exist before the big bang. Any time after the big bang God no longer exists.)

In the show there is a PLETHORA of animals and types of people in every scene almost. In the background you will always see an animal watching the main characters.
Maybe one animal is watching them, then just stops then a completely other random animal starts watching the main characters.
But an animal is always watching. Sometimes though it is just a normal animal just taking a look.
Anyways who is watching them? Its one of the Gods. And then it turns out that if God can always be watching the main characters, whos to say God isnt watching everyone all the time?

Heres a completely made up just now example.

Say in the beginning of a story a monster BURSTS from the ground, its dazed and causing havoc. The havoc only causes the monster to be more distressed.
Later in the story you learn that its afraid of needles and knives.
Then you learn it hates older men.
And then finnaly you learn that it was a son of a scientist who experimented on him with needles and knives. The son mutated bc of it and died quickly after and the father buried him in the forest.

I hope these examples are a good idea on how to do some foreshadowing.
